Mattress comprising one or more cooling devices

ABSTRACT

A mattress system, comprising a mattress comprising a top surface; and at least one cooling device configured to transfer heat away from the top surface, wherein the cooling device is configured to circulate a working fluid or thermoelectrically cool. The at least one cooling device may circulate at least one of water, ammonia, carbon dioxide, non-halogenated hydrocarbons, halogenated hydrocarbons, or liquid nitrogen. In a particular embodiment, the at least one cooling device circulates water. In another embodiment, the at least one cooling device is a thermoelectric cooling device. A mattress assembly comprising the mattress and a mattress foundation.

BACKGROUND OF THE INVENTION FIELD OF THE INVENTION

Generally, the present disclosure relates to bedding, and, more specifically, to a mattress comprising one or more cooling devices.

DESCRIPTION OF THE RELATED ART

Foam mattresses, such as viscoelastic or “memory foam” mattresses, provide desirably high levels of firmness and support for many users. However, one common consumer complaint regarding foam mattresses is that they “sleep hot,” i.e., that the mattress tends to retain the user's body heat and render the mattress less comfortable for sleep.

In an effort to alleviate the tendency of foam mattresses to “sleep hot,” workers have created airflow channels within a mattress. For example, U.S. Pat. No. 6,866,915 discloses a mattress including a viscoelastic foam layer atop a middle layer, wherein the middle layer has a non-plane surface abutting the viscoelastic foam layer. The non-plane surface may contain undulations, thereby providing airflow channels between the undulations.

However, the presence of an airflow channel in a mattress may be insufficient of itself to provide sufficient airflow to alleviate the problem of “sleeping hot.”

The present disclosure may address and/or at least reduce one or more of the problems identified above.

SUMMARY OF THE INVENTION

The following presents a simplified summary of the disclosure in order to provide a basic understanding of some aspects of the disclosure. This summary is not an exhaustive overview of the disclosure. It is not intended to identify key or critical elements of the disclosure or to delineate the scope of the disclosure. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is discussed later.

DETAILED DESCRIPTION

Various illustrative embodiments of the disclosure are described below. In the interest of clarity, not all features of an actual implementation are described in this specification. It will, of course, be appreciated that, in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

The present subject matter will now be described with reference to the attached figures. Various structures, systems and devices are schematically depicted in the drawings for purposes of explanation only and to not obscure the present disclosure with details that are well known to those skilled in the art. Nevertheless, the attached drawings are included to describe and explain illustrative examples of the present disclosure. The words and phrases used herein should be understood and interpreted to have a meaning consistent with the understanding of those words and phrases by those skilled in the relevant art. No special definition of a term or phrase, i.e., a definition that is different from the ordinary and customary meaning as understood by those skilled in the art, is intended to be implied by consistent usage of the term or phrase herein. To the extent that a term or phrase is intended to have a special meaning, i.e., a meaning other than that understood by skilled artisans, such a special definition will be expressly set forth in the specification in a definitional manner that directly and unequivocally provides the special definition for the term or phrase.

Embodiments herein are directed to mattresses comprising at least one cooling device. In one embodiment, the cooling device is a device capable for moving air, e.g., a fan, disposed at an opening of a channel through a support layer of the mattress or an electrostatic air movement device. The air movement device may provide cooling to a user of the mattress by impelling air into or withdrawing air from the channel.

In another embodiment, the cooling device is a device configured to transfer heat away from a top surface of a mattress other than by moving air, e.g., by circulating a working fluid other than air. Examples of working fluids other than air that may be circulated by such cooling devices include water, ammonia, carbon dioxide, non-halogenated hydrocarbons, halogenated hydrocarbons, and liquid nitrogen, among others. In one particular embodiment, the working fluid in the cooling device is water. Water has advantages of being non-toxic and readily serviceable by an end user.

In yet another embodiment, the cooling device is a thermoelectric cooling device. As will be known to the person of ordinary skill in the art, a thermoelectric cooling device typically comprises a plurality of n- and p-type semiconducting elements placed thermally in parallel and electrically in series. The array of semiconducting elements are placed between thermally conducting plates. When an electrical voltage is applied to an end of the semiconducting element array, a flow of DC current across the junction of the semiconductors causes a temperature difference. One of the thermally conducting plates absorbs heat which is transferred through the semiconducting element array to the other plate, which latter is in thermal communication with a heat sink.

Further, embodiments herein provide for zoned control of airflow. For example, certain channels in a mattress may be selected in order to provide airflow, wherein other channels may be left idle with respect to airflow. Moreover, airflow in channels of a mattress may be controlled in such a manner that the temperature of the mattress may be influenced by controlling the airflow. For example, airflow in certain channels in the mattress may be controlled such that regions proximate to those channels may experience increased cooling or heating. In this manner, zoned temperature control may be provided using airflow control provided by embodiments herein.

Further, embodiments herein provide for user control of airflow in a mattress. For example, a user may control the operations of the air moving devices via a remote device, such as mobile phone, a tablet, a remote control device, a laptop computer, or any electronic device that is capable of communicating with a control device for controlling the operations of the air moving devices in the mattress. In some embodiments, an application (app) may be used by a user of a mobile device to control the operations of air moving devices.

Turning to FIG. 1, a stylized top view of a mattress 100, in accordance with embodiments herein, is illustrated. The mattress 100 has a generally rectangular profile in top view, with opposed shorter sides 103, 105 each having a dimension 101, and opposed longer sides 104, 106 each having a dimension 102. Typically, the shorter sides 103, 105 provide the head and foot ends, respectively, of the mattress 100, and the longer sides 104, 106 provide the sides of the mattress 100.

FIG. 2 illustrates a stylized side view of the mattress 100, in accordance with embodiments herein. The side view shows one of the longer sides, side 104.

The mattress 100 includes a first layer 120. The first layer 120 comprises at least one channel 122, e.g., as shown in FIG. 2, five channels 122 a, 122 b, 122 c, 122 d, and 122 e, each extending from a first side 104 to a second side 106 of the mattress 100. Each channel has a first opening at the first side 104 of the mattress 100 and a second opening at the second side 106 of the mattress 120. Disposed in at least one channel 122 is an air movement device 126, such as a fan, e.g., as shown in FIG. 2, two fans 126 a and 126 b, with a first fan 126 a disposed in channel 122 a and a second fan 126 b disposed in channel 122 b. Although the channels 122 a-e are depicted as extending laterally from the first side 104 to the opposed second side 106, the invention is not limited to this depicted embodiment.

For ease of illustration, embodiments herein are described in terms of the air movement device being a fan. However, those skilled in the art having benefit of the present disclosure, would appreciate that other type of an air movement devices may be implemented in embodiments herein. For example, the air movement device 126 may be electrostatic air mover. For example, the drawings represented by the fans 126 a and 126 b may be electrostatic air moving devices. In one embodiment, the electrostatic air moving device 126 may comprise two oppositely charged electrodes, wherein a first electrode may generate ions by electrical means, e.g., a corona discharge. The ions may then be attracted to a second electrode, which has an opposite charge as the first electrode, which may cause movement of air. Accordingly, the fans 126 described herein may be a device having blades to move air, or alternatively, may use electrical means, (e.g., electrostatic air movement) to move air.

In some embodiments, wherein the air moving device 126 is an electrostatic air moving device, a corona discharge may be utilized to cause an air movement. For example, discharge of corona may be used for implementing an air velocity electrostatic pump, i.e., a corona pump.

In an electrostatic air device, ions interacting with an electric field may cause an acceleration of the ions. This flow of ions provides causes an airflow within an air flow region, such as a duct or channel system within a mattress. The airflow may be controlled by the geometry of the electric field as well as the intensity of the electric field. In some embodiments, the electric field may run parallel to the walls of a channel or duct through which the airflow is guided.

In some embodiments the airflow, whether generated using an electrostatic air moving device 126 or one or more fans (126 a, 126 b), may be controlled by a remove wireless device, such as a mobile phone device, a tablet device, a laptop computer, etc. For example, an application installed on a mobile phone may be capable of communicating with the air moving device and controlling one or more functions.

In some embodiment, the air moving device may comprise one or more small fans, e.g., micro fans. In many embodiments, each fan 126 may have any case size, blade size, speed, or other parameters known in the art. In one embodiment, all fans 126 in a single mattress 100 may be identical in size, speed, and other parameters. In embodiments, it may be desirable for the fans 126 to have relative large case and blade sizes and relatively slow speeds, in order to provide a given amount of airflow with relatively low noise, given that the noise of a fan is generally correlated with the fan's speed.

Each fan 126 may receive electrical power from one or more sources. In one embodiment, each fan 126 may be powered by direct current (DC), e.g. by one or more batteries. In one embodiment, each fan 126 may be powered by alternating current (AC), such as through cabling electrically connected to a transformer connected to a main electrical line.

In one embodiment, each fan 126 is configured for inductive charging. Inductive charging may provide greater convenience than that provided by alkaline, nickel-cadmium, or other batteries, which require frequent replacement, and may also provide greater convenience and esthetic quality than that provided by electrical cables, which require routing and positioning into and/or along the mattress 100.

The first layer 120 may comprise a visco-elastic foam, a non-viscoelastic foam, or a polyurethane foam, among other materials. In one embodiment, the first layer 120 comprises a non-viscoelastic foam. The first layer 120 may be referred to herein as a “support layer.”

In the depicted embodiment, the mattress 100 may also comprise a comfort layer 130 disposed directly above the first layer 120. The comfort layer 130 may comprise any material and/or assemblage of sublayers suitable for providing comfort to a user reclining on the mattress 100. In one embodiment, the comfort layer 130 comprises a foam. In a particular embodiment, the comfort layer 130 comprises a viscoelastic foam. For example, the viscoelastic foam may have a density from about 25 kg/m³ to about 250 kg/m³, such as from about 50 kg/m³ to about 120 kg/m³. In an even more particular embodiment, the viscoelastic foam may have a density of about 80-85 kg/m³. Alternatively or in addition, the viscoelastic foam may have a hardness from about 5 N to about 20 N, such as a hardness of about 10 N. Alternatively or in addition, the comfort layer 130 may include a base sublayer and a pillow-top sublayer.

The first layer 120 and the comfort layer 130 may be bonded together by any suitable adhesive. The first layer 120 and the comfort layer 130 (if any) may be assembled using any process and/or equipment known in the art.

For the avoidance of doubt, and in accordance with practice before the United States Patent and Trademark Office, none of the present figures are to scale.

FIGS. 3-5 each show a cross-sectional view of the first layer 120 taken along line A-A′ in FIG. 2. Each of FIGS. 3-5 show that the fans 126, e.g., fan 126 a and fan 126 b, are disposed at the first opening or the second opening of their respective channels 122 a and 122 b. In FIGS. 3-5, the direction of airflow generated by each fan 126 a and 126 b is shown with a heavy arrow.

In FIG. 3, both the first fan 126 a and the second fan 126 b are configured to impel air into their respective channels 122 a and 122 b.

In FIG. 4, both the first fan 126 a and the second fan 126 b are configured to withdraw air from their respective channels 122 a and 122 b.

In FIG. 5, the first fan 126 a is configured to impel air into the first channel 122 a and the second fan 126 b is configured to withdraw air from the channel at the opening of which it is disposed, namely, second channel 122 b.

Any arrangement of airflow directions, e.g., impelling air into or withdrawing air from a channel, may be implemented by the person of ordinary skill in the art having the benefit of the present disclosure.

In the depicted embodiments of FIGS. 2-5, the second fan 126 b is shown disposed in the first opening of the second channel 122 b. By “first opening of the second channel 122 b” is meant the opening of the second channel 122 b that is on the same side (104 or 106) of the mattress 100 as the opening of the first channel 122 a in which the first fan 126 a is disposed. In other embodiments, not shown in FIGS. 2-5, the second fan 126 b may alternatively be disposed at the second opening of the second channel 122 b (i.e., the opening of the second channel 122 b on the opposite side of the opening of the first channel 122 a at which the first fan 126 a is disposed), or at the opening of the first channel 122 a at which the first fan 126 a is not disposed.

FIGS. 6-8 depict another embodiment of a mattress according to the present disclosure. In the side view of the mattress 600 shown in FIG. 6, elements that are identical to those shown in and described with reference to FIGS. 2-5 are assigned the same reference numerals and need not be described further. Elements that are similar to those shown in and described with reference to FIGS. 2-5 are assigned reference numerals identical in the tens and ones digits, differing only in the hundreds digit, with relevant differences described below.

In the side view of the mattress 600, only one fan, first fan 626 a, is visible at a first opening of channel 122 a. The cross-sectional views along line A-A′ shown in FIGS. 7-8 show a second fan 626 b. In FIGS. 7-8, the first fan 626 a is disposed at a first opening of the channel 122 a and the second fan 626 b is disposed at the second, opposite opening of the channel 122 a.

In FIG. 7, the first fan 626 a impels air into the channel 122 a and the second fan 626 b withdraws air from the channel 122 a.

In FIG. 8, the first fan 626 a withdraws air from the channel 122 a and the second fan 626 b impels air into the channel 122 a.

Turning to FIGS. 9-10, a mattress 900 according to another embodiment of the present disclosure is depicted. In addition to fans 126 a and 126 b disposed at openings of channels, the mattress 900 further comprises at least one support member in at least one channel. Desirably, the at least one support member is configured to permit a flow of air therethrough or therearound.

Regardless of the particular embodiment of the foam spring 124, an advantage of a foam spring 124 as represented in FIGS. 9-10 is that, when the spring 124 is compressed, the foam spring 124 has a reduced tendency to bulk out in a radial or lateral direction and hence the diameter of the tubular spring is essentially preserved.

Another advantage of the foam spring 124 is that the resilience, compressive strength, and useful lifetime of the spring 124 may be enhanced, even when lower density foam is used for its construction.

Further, the disclosure is not necessarily limited to cylindrical foam springs 124 c, but can also be applied to other shapes of springs, such as polygon shapes (e.g., pentagon, hexagon, heptagon, etc.)

Alternatively, or in addition, and as depicted in FIGS. 9-10, at least one foam sphere or hemisphere, such as foam spheres 925 e, may be present in one or more channels, e.g., channel 122 e. In the side view of FIG. 9, in each channel 122 a-122 e, only one foam sphere 925 e is visible. Arrangements of foam spheres or hemispheres in channels 122 will be described in more detail below. Foam spheres 925 e or hemispheres generally have a spherical or hemispherical resilient body made of foam. In one embodiment, the foam spheres 925 e or hemispheres comprise polyurethane foam. The foam spheres 925 e may have some compressibility when under load, thereby providing improved comfort to a user of the mattress 100. Alternatively, the foam spheres 925 e may resist compression when under load, thereby relieving pressure points to the user of the mattress 100.

The person of ordinary skill in the art will understand that foam spheres 925 e and foam hemispheres would have the property of permitting airflow therearound, e.g. at the corners of the channel 925 e in side view.

Turning to FIG. 10, a sectional view taken along the line A-A′ in FIG. 9, in accordance with embodiments herein, is shown. This sectional view looks down across the middle of the first layer 120. As shown, each channel 122 a-122 c comprises a plurality of foam springs. FIG. 10 illustrates sets of foam springs 124 a-124 c, appearing as rounded features, configured within respective channels 122 a-122 c. The channels 122 a-122 e may be formed from multiple first layer portions.

Each channel 122 a-122 c may comprise the same number of foam springs 124 or different numbers of foam springs 124.

As depicted in FIG. 10, one channel (122 e) may comprise a plurality of foam spheres 925 e.

The embodiment shown in FIGS. 9-10 is exemplary in the number of channels 122 and the number and type of support members in each channel 122. In embodiments, not shown, one or more of the channels 122 may exclude support members. A channel 122 without support members therein may be a channel 122 at an opening of which a fan 126 may be disposed. The person of ordinary skill in the art may vary these and other parameters of the mattress 900 as a routine matter and remain within the spirit of embodiments herein.

Turning to FIGS. 11-12, mattresses 1300 and 1400, each comprising two or three intermediate layers, respectively, are shown.

FIG. 11 depicts a mattress 1300 comprising a polyurethane layer 110 and two support layers 120 and 1320. The first support layer 120 may be as described above, such as with reference to FIGS. 9-10. The second support layer 1320 is similar to the first, in that it may comprise the same material and may also comprise at least one support element (e.g., foam springs 124 f-124 m) disposed in a channel 1322. The second support layer 1320 depicted in FIG. 11 comprises a single channel 1322. In other embodiments (not shown), the second support layer may comprise a plurality of channels.

FIG. 12 depicts a mattress 1400 comprising three support layers 120, 1320, and 1420. The first support layer 120 and the second support layer 1320 may be as described above. The third support layer 1420 may comprise a single curved channel 1422.

In embodiments wherein a mattress comprises one support layer, the support layer may be any one of the support layers 120, 420, 620, 1320, 1420, and 1421, along with others not depicted but described herein. For example, any support layer shown comprising one or more support elements disposed in a channel may be substituted with an otherwise-identical support layer lacking support elements in a channel, or vice versa. In such embodiments, a single support layer is simultaneously the bottom-most support layer and the uppermost support layer.

In embodiments wherein a mattress comprises two, three, or more support layers, each support layer may comprise any one of the support layers 120, 420, 620, 1320, and 1420, along with others not depicted but described herein. Any one of the support layers 120, 420, 620, 1320, and 1420, along with others not depicted but described herein may be duplicated in a mattress comprising two or more support layers. Alternatively or in addition, in any mattress comprising two or more support layers, any one of the support layers 120, 420, 620, 1320, and 1420, along with others not depicted but described herein. may be arranged in any order, i.e., any support layer 120, 420, 620, 1320, or 1420, or any other not depicted but described herein, may be the bottom-most support layer, the uppermost support layer, or at any position between the bottom-most and uppermost support layers.

In another embodiment, as depicted in stylized side view in FIG. 13, the present disclosure relates to a mattress assembly 1500, in accordance with embodiments herein. The mattress assembly 1500 comprises a mattress as described above, such as a mattress 100 comprising a plurality of channels 122 a-122 e and two air movement devices 126 a and 126 b, (e.g., fans, electrostatic air movement devices, etc.), each disposed at an opening of a channel. The mattress assembly may comprise other mattresses described herein, with such other mattresses being substitutable for the mattress 100 in the mattress assembly 1500 as a routine matter for the person of ordinary skill in the art.

The mattress assembly 1500 may also comprise a control unit 1550 capable of controlling the operation of the air movement devices 126 a, 126 b.

Exemplary mattress foundations 1540 include, but are not limited to, box springs; metal frames; and adjustable supports, including electromechanically adjustable supports; among others.

FIG. 14 illustrates a stylized depiction of the mattress foundation of FIG. 13, in accordance with embodiments herein. In some embodiments, the mattress foundation may be comprised of two or more sections. For example, the mattress foundation 1540 may comprise a 1^(st) section 1640 a, a 2^(nd) second section 1640 b, a 3^(rd) section 1640 c, and a 4^(th) section 1640 d. Some or all of the sections 1640 a-1640 d may be configured to move independently, as indicated by the dotted lines over the 1^(st) section 1640 a, the 3^(rd) section 1640 c, and the 4^(th) section 1640 d.

Each of the 1^(st) through 4^(th) section 1640 a-1640 d may be connected to pivot points to allow for independent movements. For example, the 1^(st) section 1640 a and the 2^(nd) section 1640 b may be movably coupled to a 1^(st) pivot point 1610 a. In one embodiment, the 1^(st) section may move up and down about the 1^(st) pivot point 1610 a. The 1^(st) section 1640 a may be at the head of a bed.

The 2^(nd) section 1640 b and the 3^(rd) section may be movably coupled to a 2^(nd) pivot point 1610 b. In one embodiment, the 3^(rd) section may move up and down about the 2^(nd) pivot point 1610 b.

The 3^(rd) section 1640 c and the 4^(th) section 1640 d may be movably coupled to a 3rd pivot point 1610 c. In one embodiment, the 4^(th) section may move up and down about the 3^(rd) pivot point 1610 c. In one embodiment, the 4^(th) section may be at the foot of a bed. Those skilled in the art would appreciate that additional sections and/or pivot points may be implemented onto the mattress foundation 1540 and remain with the spirit and scope of embodiments herein.

In some embodiments, one or more of the pivots 1610 a, 1610 b, 1610 c may comprise a motor that may cause the pivots to be controllably operated. In some embodiments, the pivots 1610 a, 1610 b, 1610 c may be controlled by one or more external motors. In some embodiments, the pivots 1610 a, 1610 b, 1610 c may be operated using a remote electronic device, such as mobile phone, a laptop, a television, etc.

Next, FIG. 16 shows a top cross-sectional view of a mattress system 1700 according to an embodiment of the present disclosure. The mattress system 1700 comprises a cooling device 150 that is configured for liquid cooling. The cooling device 150 comprises a conduit 1754, which may be disposed within a support layer 120 of the mattress system 1700, and a reservoir/pump/thermoregulator unit 1752. In the unit 1752, the thermoregulator controls the temperature of a liquid in the reservoir, such that the liquid has a desired temperature, and the pump circulates the liquid through the conduit 454. In embodiments wherein the cooling device 150 is configured for liquid cooling, the thermoregulator may comprise a radiator and a fan configured to transfer heat from the liquid to ambient environment, and the pump impels cooled liquid into the conduit 1754. The liquid may conveniently be water; however, the person of ordinary skill in the art having the benefit of the present disclosure may configure a cooling device to use a working liquid other than water, such as ammonia, carbon dioxide, non-halogenated hydrocarbons, halogenated hydrocarbons, or liquid nitrogen, among others.

The person of ordinary skill in the art having the benefit of the present disclosure may apply the principles expressed in these embodiments to implement the cooling device 150 as a thermoelectric cooling system.
